+## Installation
+
+Install this package through [Composer](https://getcomposer.org/).
+
+Edit your project's `composer.json` file to require `longman/laravel-multilang`
+
+Create *composer.json* file:
+```json
+{
+    "name": "yourproject/yourproject",
+    "type": "project",
+    "require": {
+        "php-telegram-bot/laravel": "~0.1"
+    }
+}
+```
+And run composer update
+
+**Or** run a command in your command line:
+
+    composer require php-telegram-bot/laravel
+
+In Laravel 5.5 the service provider will automatically get registered. 
+In older versions of the framework just add the service provider in `config/app.php` file:
+
+```php
+PhpTelegramBot\Laravel\PhpTelegramBotServiceProvider::class,
+```
+
+Copy the package config and migrations to your project with the publish command:
+
+    php artisan vendor:publish --provider="PhpTelegramBot\Laravel\PhpTelegramBotServiceProvider"
+
+
+After run migration command
+
+    php artisan migrate
+
+## Usage
+
+You can inject `PhpTelegramBot\Laravel\PhpTelegramBotContract` in anywhere and use bot instance
+
+For example:
+
+```php
+<?php
+namespace App\Http\Controllers;
+
+use PhpTelegramBot\Laravel\PhpTelegramBotContract;
+
+class CustomController extends Controller
+{
+    public function handle(PhpTelegramBotContract $telegram_bot)
+    {
+        // Call handle method
+        $telegram_bot->handle();
+        
+        // Or set webhook 
+        $telegram_bot->setWebhook($hook_url);
+        
+        // Or handle telegram getUpdates request
+        $telegram_bot->handleGetUpdates();
+    }
+}
+
+```
